I don't know. Do you know how they power up during start up.
TE beat me to it, but no, they don't rely on "conventional" plants and most don't take "two weeks" to start up, the time between a forced shut down and start up is greatly influenced by inspections, not mechanical requirements. You do need to look into how they operate a little more.
We take 2 weeks, remember the big black out in the North East, and the one in Florida, I'm just referring to what is, not what could be. Nukes don't simply turn on an off with a flick of the switch. Restarting is a process. During this process, the grid needs to be stable. These shut downs were a glitch, that I'm sure was looked at. No offense intended. There are also issues with phase syncronization when coming into the grid.
Kit, I'm not blasting Nuclear Power, Done safely, I will support it. I recognize that we are grossly under powered. The solution is years away. Natural Gas and Hydro compliment the Grid too, and also have their own advantages. They should not be abandoned.
I'm also trying to learn. Navy 1960 has been very helpful. Why not check into reprocessing spent fuel, and if it checks out for you, support that too. It seems to make allot of sense.
Love that Avatar. It's one of my favorites.
